Red-flag it! Jonah Hill may want to use a journal the next time he writes down his food intake. The True Story actor revealed during The Tonight Show Starring Jimmy Fallon on Tuesday, August 2, that he once accidentally emailed Drake what he eats.

It all started when Hill wanted to lose weight after filming the drama War Dogs last year. He hired a nutritionist after speaking with his 21 Jump Street costar Channing Tatum.

"I wanted to get into better shape so I called Channing Tatum and I said, 'If I eat less and go to a trainer, will I get into better shape?'" Hill, 32, recalled to Fallon, 41. "And he said, 'Yea, you dumb motherf--ker.'"

The crowd burst into laughter at Tatum's blunt response — and even more when Hill revealed what happened next. The Oscar-nominated actor sent his food diary via email to his doctor, only to notice hours later that it actually went to the rapper, 29.

"Drake, who I don't know well at all, just got an email that said ‘yogurt, salad, chicken.’ And then it just said ‘Jonah’ at the end of it," Hill said, cracking up.

"He didn't write back. Never spoke to the guy," he added. "Another guy I got to duck for the rest of my life! A long laundry list of people I can never speak to [again]."
